Abstract

L'invention concerne des procédés permettant la modification de surface d'un substrat polymère hydrophobe pour augmenter sa mouillabilité. Le procédé comprend les étapes de prétraitement du substrat polymère hydrophobe par un premier plasma généré par radiofréquence (RF) et un second plasma généré par RF, le premier plasma et le second plasma étant appliqués de façon séquentielle; de revêtement du substrat polymère hydrophobe par un revêtement hydrophile; et de polymérisation du revêtement hydrophile sur le substrat polymère hydrophobe par exposition à un troisième plasma généré par RF.
